Argument event is not working in ggadjustedcurves and surv_adjustedcurves

[barbosawf]

Expected behavior

I tried to use the argument 'event' in the paremeter fun of both functions ggadjustedcurves and surv_adjustedcurves. I was expecting a bottom-up curve just like with ggsurvplot. Curves remained from top to bottom.
